Most adult Christmas elf costumes are made from polyester; trims and accents often use faux wool, faux fur, or faux leather.
Listings commonly recommend machine washing and then line-drying or laying flat to dry. Descriptions also note that many costumes use durable, easy-to-care-for synthetic fabrics.
Typical sets include a core garment (dress, shirt, or jacket), an elf-style hat, and a waist belt. Many sets also include pants, stockings or socks, and footwear covers (bootcovers or shoe covers). Some women's dress sets add a hooded cape, gloves, or novelty headbands.
Many sets include bootcovers or foam-backed shoe covers that fit over shoes; some sets list booties or shoe-cover styles with elastic ankles or hook-and-loop fastenings.
Women's dress styles often feature short puffy sleeves with a pointed flat collar. Other costumes use jester-style collars, and some jacket styles include faux-fur collars and fur-trimmed cuffs.
Piece counts vary by style; examples in listings include 3-piece dress sets, 6-piece apparel sets, and 8-piece apparel sets.
Common accessories include an elf hat and a waist belt; some sets also include a hooded cape, gloves, or novelty headbands such as reindeer antlers.
